It’s a good Idea to deinterlace the video and to convert the .mov provided into an image sequence, and I will tell you guys how to do that in the next video.
This is my first tutorial, I am sure I will get better as I go along, but please let me know some feedback. Too fast? too slow? to boring? etc. I’d be glad to hear. Thanks and I look forward to posting more videos.

I thought the tutorial was pretty informative, well done!
Very more interesting could be a replacement sky with camera movement…
Loved rreading this thanks
